Intriguing things are afoot at Twitter HQ, no doubt many of them centred on generating revenue for the four-year-old company. It should come as no surprise, then, that a new account called Earlybird has launched, seemingly primed to channel offers, deals and other exclusive goodies from outside retailers.

Earlybird looks the likely natural progression of other recently launched revenue streams, promoted tweets and sponsored trends. Speaking to Read Write Web, Twitter's Carolyn Penner gave nothing away: "There are interesting things in store for @earlybird. Keep waking up early and you might be the first to find out what they are."

RWW'S Michael Kirkpatrick ruminates that Early Bird could be the starting place for a number of vertical platforms such as EarlyBirdElectronics and EarlyBirdMusic, offering selected deals to opt-in customers in a similar way to Keynoir and Groupon.

If early reports from Coca-Cola are anything to go by, promoting products directly through Twitter is proving a lucrative return on modest investment. Speaking to the Financial Times last week, Carol Kruse, vice-president for global interactive marketing at Coca-Cola, said the number of impressions (views of the sponsored trending topic) Coca-Cola had received in the short period from launch had been "phenomenal" – 86m in 24 hours with an "engagement rate" of 6%, compared with the average 0.02% of users engaging with a standard online advertisement.

Kruse also indicated this new form of advertising was relatively inexpensive compared to traditional online ads.

For now, Earlybird remains a private account with fewer than 300 followers – but by tomorrow morning? We'll follow with interest.
